METHOD FOR GROUND-BASED EXPLORATION OF OIL DEPOSITS BY MEANS OF RADIO-WAVE DETECTION OF AIR ION ANOMALIES OVER OIL DEPOSITS Russian patent published in 2019 - IPC G01V9/00 G01V3/16 G01V3/08 

FIELD: geophysics.

SUBSTANCE: disclosed method relates to geophysics and can be used for remote radio-wave detection of oil deposits on land. Method is based on presentation of oil deposit as natural, actively functioning electrochemical system, called "fuel cell". Geodynamic processes in the deposit lead to the fact that part of the hydrocarbon substrate of the deposit changes into the form of ionized molecules of alkanes and nanoparticles of metals inherent in oil and is carried out with free capillary moisture into the surface atmosphere. As a result, an electrically active abnormal concentration of ions of hydrocarbons, charged nanoparticles and electrons interacting with the magnetic field of the Earth is formed over the oil deposit. Plasma-like medium of anomaly generates manifestation of high-frequency electric conductivity in it, which will be reflected on characteristics of radio transmitting equipment operating within anomaly. Characteristics of air ion anomaly are not related to geological features of oil deposit. This determines universality of proposed method of regional oil exploration by means of radio wave detection of air ion anomalies over oil deposits. Method of determining integral characteristics of an air ion anomaly uses a "method of transforming an antenna pattern" based on measuring the intensity of the electrical field component and plotting the directivity pattern of the antenna emitters. In view of significant size of sampling networks of areas promising for hydrocarbons, as well as number of field intensity measurements at each point of sampling network, proposed method is based on mandatory location of probing radio equipment of GR and IR on unmanned aerial system (UAS), consisting of two unmanned quadcopters with navigation equipment and ground mobile FCC with operator.

EFFECT: high information value of the obtained data owing to the creation of a unified unmanned radio-wave method for detecting hard-to-identify oil deposits in complex landscape-geomorphological conditions.
